Specification of Letters Patent.

Original application filed. October l, 1914. Serial No. 864,420. Dividedand this application filed July 6,

F0 all whom it may concern:

Be it known that T, SIDNEY RosENFnLD, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a. certain new and useful Improvement in Bushings, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings.

This invention relates to bushings and to the manner of forming theconnection between such bushings and the cooperating metallic supportingmembers therefor (such as the bodies or heads of barrels, kegs or cans)whereby a close, non-leaking connection may be formed between suchbushings and the surrounding metal bodies and whereby this connectionmay be formed in a particularly economical and eflicient manner. Theapplication herein is a division of my application No. 864,420, filedOctober 1, 1914:.

In the drawings forming part hereof, Figure 1 represents a perspectiveView of my bushing prior to its application to the cooperating metalbody; Fig. 2 a perspective view of the metal body as prepared for thereception of the bushing; Figs. 3 and 4 details in section illustratingthe manner in which the bushing is secured in place; and Fig; 5 aperspective view of the bushing and the surrounding metal body to whichit is united.

While the invention disclosed herein is capable of general applicationwherever it may be desirable to unite a hollow or tubular article to ametal sheet or body, it is particularly useful where the tubular body isa bushing and where such body is internally threaded for the receptionof an externally threaded body, such as a faucet or a plug; since,through the manner of uniting the bushing to the metal body, not only isa tight or leak-proof joint provided between the exterior surface of thebushing and the metal body, but this connection. is not endangeredthrough the rotary or torsional strain which may be applied to thebushing through the screwing or unscrewing of the faucet therewithin.

Describing by reference characters the various parts illustrated herein,1 represents the body or neck of an internally threaded bushing, theinternal thread being represented at 2. The bushing is provided with aSerial No. 38,086.

base flange 3 projecting therefrom intermediate of the ends thereof. Forconvenience of description, it will be assumed that the bushing occupiesa position wherein the threaded bore will extend in a verticaldirection, and the terms top, bottom, upper and lower will be used inaccordance with this assumption, it being understoochhowover, that I donot propose thereby to limit the use of the bushing to such verticalposi tion of the bore or axis. The outer surface of the bushing isconcaved from the top thereof to the outer edge of the flange .3,whereby there will be a progressive diminution in the thickness of thebody from the flange 8 to the upper end of the body. The bottom of thebushing body extends below the flange, as shown at 4-. The outer wall ofthe bushing is substantially concentric with the inner wall, with theexception that a suitable number of ears or lugs 5 are provided, whichlugs or cars project laterally beyond the outer wall and preferablyextend from the top of the bushing body to and merge with the flange 3.These lugs or cars are preferably of the shape shown in Fig. 1, having avertical outer face 5 and vertical side faces 5 the face 5 beingpreferably parallel with the axis of the bush ing and the'faces 5 beingshown as substantially parallel to each otheralthough any other angularform may be given to these lugs or ears.

6 denotes a metallic shell or body to which the bushing is to beapplied. This shell or body may be the head or curved side of a barrelor keg, or any other article. The metal body 6 is shown as having anaperture 7 therein, said aperture being preferably circular and ofslightly greater diameter than the diameter of the bushing adjacent tothe flange 3. The aperture 7 is provided with lateral notches orrecesses 8 corresponding in shape to the lugs or ears 5 and adapted toreceive the same. As-many lugs or ears and corresponding notches orrecesses will be provided as occasion may require, two such lugs or earsand two such notches or recesses being shown.

With the parts arranged as described, the bushing may be convenientlyconnected to the metal body 6 in the manner illustrated in the drawings,wherein 9 denotes a movable die member having a circular opening in thelower face thereof, said opening being Patented Dec. a, ilHft.

preferably of a diameter intermediate, between the inner and the outerdiameter of the bushing body 1. The bottom of the die 9 is fiat or planeas indicated at 10. This die member 9 is provided with a reciprocableplunger 11. having an operating rod or stem 12. 13 denotes the fixed orbottom 'memberof' thedie, said die having an an nular recess 14: whichis adapted to receive the lower portion of the flange 3 of the bushingand the part ofthe'bushing body therebeneath, indicated at 4.

In operation, the bushing will be inserted into the opening 7 of themetal plate with the'lugs or ears 5 within the corresponding recesses 8and the top of the flange 3 against the bottom of the plate or body 6.The bushing and plate will then be applied to the die member 13 in themanner shown in Fig. 3. The die head 9 will then be forced downwardly,whereupon the inner edge of the bottom face 10 of this die will engagethe outer portion of the top of the bushing body 1, along the dottedline 15 shown in Fig. 1. This will result in forcing theouter portion ofthe bushing body downwardly and outwardly, the die member 9 exercising asort of shearing action on the metal at the exterior portion of the body1 and spreading it into close engagement with the wall of the aperture 7in'the plate 6, and also spreading the lugs or ears 5 outwardly in likemanner,.but without affecting the internal diameter of the bushing.Theaperture 7, the height and outer diameter of the bushing body 3, andthe internal diameter of the .guide member 9 will be such that, whenthis member strikes the plate 6 (as shown in Fig. 4:) the metalformingthe outer portion of the bushing will have been spread outwardlyto completely fill andtightly fit against the wall which bounds anddefines the aperture 7. .The walls or faces of the lugs 5 will be forcedin like manner into tight engagement movable die member, the plunger rod12 may be operated to disengage these parts.

From the foregoing description it will be apparent that I have produceda bushing and a mode of connecting the same to a surrounding metal bodywhich will enable the connection to be made in a particularly ellicientand economical manner.

Having thus described my invention, what I claim is 1. The combination,with a metal plate having an aperture with one or more laterallyprojecting notches, of a bushing having a flange adapted to engage onesurface of the plate and having one or more lugs corresponding to thenotch or notches, the metal of the bushing body being expanded outwardlyinto locking engagement with the wall defining the aperture in the metalplate, with the lug or lugs engaging the metal bounding the notch ornotches.

2. The combination, with a metal plate having an aperture provided withone or more laterally projecting notches, of a bush ing having a flangeand a body, the flange being adapted to engage one surface of the plateand the body being adapted to extend through the aperture in the plateand provided with one or more lugs corresponding to and adapted to enterthe notch or notches, the metal at the outer portion only of the bushingbody being expanded outwardly into locking engagement with the walldefining the aperture in the metal plate, and the lug or lugs beingexpanded into close engagement with the metal bounding the notch ornotches.

3. The combination, with a. metal plate having an aperture therethrough,of a bush ing having a flange and a body, the flange being adapted toengage one side of the plate adjacent to the aperture and the body beingadapted to extend through the aperture in the plate, the metal at theouter portion only of the bushing body being expanded outwardly intolocking engagement with the wall defining the aperture in the metalplate.

In testimony whereof, I hereunto afiix my signature in the presence oftwo witnesses.
